- muscle dilating causes iris muscle to contract, can close the angle more, cause more pain

- eye surgery definitive
- multiple drugs used while waiting surgery

- elderly
- steroid usage: remodel of trabecular meshwork, less drainage
![](https://photos.thisispiggy.com/file/wikiFiles/K1d1XGl.jpg)
- most patients primary
- uveitis: impaired drainage

- disc cup: bright area 1/3 size of optic disc
- glaucoma: optic cup very big

- closes iris, improves angle
- contracts ciliary muscle

- "F": PGF2a
- LA tan sandals: latanoprost (PGF2a)
- World traveler boots: travoprost (PGF2a)
- Leaking eyeballs: latanoprost and travoprost treat glaucoma by increasing aqueous humor outflow (not production)
- Brown sunglasses: latanoprost and travoprost can produce brown pigmentation in iris
